The less expensive Lumia 435 comes with a four-inch display, and modest two-megapixel front camera. The more expensive 532 features the same display but includes a more powerful camera and access to some high-speed networks, and the possibility of dual SIM for using more than one phone number.

The move comes after Google’s announcement last year that it would begin selling smartphones for under USD 100 in emerging markets to boost the Android operating system.

Other low-cost handsets aimed at the same markets include some using alternative operating systems including Firefox from Mozilla.
